The Olympus 60mm is relatively light, built of plastic lens, however, is comparatively large for MFT standards. It is water resistant and has to prevent the camera side a rubber ring, the penetration of spray water into the camera. Together with a splash-proof camera (eg Olympus OM-D) can be trusted even in moderate rain you look at it.
At the lens there is a knob which allows you to restrict the focus range, ie on 0.19-0.4m (for macros), 0.4m-infinity, or the entire focal range. In a fourth position can be focus the lens at 0.19m (corresponding to a maximum magnification ratio of 1: 1). There the button but does not lock, you have to keep it rotated. This function will be used primarily for manual focus, as you would otherwise have to screw here much the focus ring to undendlich of 1: 1 to come. Focusing works, as with many other MFT lenses, indirectly: As you turn the focus ring to focus the camera on the built-in focus motor. The manual focusing is very accurate, but just at the expense of speed. The autofocus will work for non-macro distances with similar speed and precision as in the other my fixed focal lenses. For macro photography you should (as with SLRs) Focusing manually and use a tripod.
The sharpness is very good even at full aperture. For portrait or other non-macro shots of the lens is a good, though not dazzling, bokeh. Due to the small sensor size of MFT cameras you will get this but rather to see in close-ups. Longitudinal chromatic aberration (color fringing on highlight objects that are not to focus) I could not find noticeable.
The lens hood is usual for Olympus, not included. This is offered as a rip-off of Olympus for an inflated price as an accessory.
Since Olympus cameras have a built-in stabilization on the sensor, this lens has no further image stabilization. The Panasonic 45mm macro, unlike one that is not needed or supported by Olympus cameras. For true macro photography, this plays a subordinate role, as it can compensate for very small inaccuracies so big enlargements. In addition, the lens has a very good light intensity. For tele / portrait photography an image stabilizer can still be useful in certain situations.
Following is a summary of the features that were crucial to me for evaluation:
+ Lichtstark (f / 2.8)
+ Super sharp
+ Light
+ Precise manual focus, good autofocus
+/- Relative size
+/- Good (but not outstanding) Bokeh
- Short working distance
- No lens hood
- No image stabilization for Panasonic cameras
So to sum it a fantastic macro lens for MFT. A strong buy recommendation for Olympus cameras. Panasonic owners need to consider whether they want for the image stabilizer to give up the longer focal length and the better price.
